wall blocking light

[jeremybrowntattoos]

hello, I have four Kessel a360 X lights hooked on my 150 reef tank, the tank is in the wall, so part of the wall is blocking the light, I will attach pictures. My question is, can this affect the lighting that my corals get in the front of my tank?

Yes, but you'd need to take some readings with a PAR meter to ascertain to what extent. It may be a minimal loss (or not).
